Growth of salamanders over time during summers 2006-2008. A. t. melanostictum larvae collected in YNP during the summers of 2006-2008. Blue rings denote larvae collected from permanent environments (n = 81); gray rings denote larvae collected from ephemeral environments (n = 405). Curves show Von Bertalanffy models of growth: growth of larvae from permanent environments shown with blue line; growth of larvae from ephemeral ponds shown with gray. On the y axis, a shows date when the first ephemeral pond dried (30 June); b shows first date that an emerging metamorph was found in an ephemeral pond (10 July); c shows earliest date that an emerging metamorph was found in a permanent pond (19 July); d shows earliest date a recently mature paedomorph was found in a permanent pond (30 July). On the y axis, e shows the size of the smallest metamorph captured (45 mm ≅ SVL_m).
